From the project
Prototype card for the OreSat bus. Requires the OreSat Backplane.
The OreSat MCXN Proto Card is a generic OreSat card based on the NXP MCXN947 microcontroller. It has an OreSat Power Domain (OPD), a CAN interface, an OreSat Card Debug port, a bzillion test points, and a 0.1 inch hole prototyping area.
The proto card also has the OreSat auxiliary connector and 3 RF backplane connectors, but these are not placed since they're not usually used.
